[U-Boot] [PATCH v2 2/5] sifive: fu540: Enable OF_SEPARATE

[Jagan Teki]

Use dts support from U-Boot via OF_SEPARATE instead of depending from
opensbi.

This would help to make the necessary changes in drivers and devicetrees
in uboot tree itself. this feature would also be helpful to not pass
dtb during opensbi builds.
